Secondly, the key point of quartz stone countertop quality can be seen from the composition. First of all, timely crystal is better, which is not a big common problem. Then, the proportion of seasonal crystals should be correct, reaching 90%. The last key point is resin. These timely crystals are bonded together by resin. Many domestic manufacturers cut corners to reduce the proportion of resin, resulting in insufficient adhesion or insufficient strength due to the use of inferior resin. Then when you use it, you will feel rough, sandy and rustle, and some will lose powder, and soy sauce will easily pollute the countertop. There will be no specular reflection under the light, and there will be a matte feeling.
There is no way to solve it in the end. Manufacturers may say that polishing and surface crystallization cannot be eradicated at all. Such a countertop is unqualified and can't be used in the environment of frequent contact with acid, alkali, salt and oil. If you want to achieve the effect of high hardness, corrosion resistance and easy cleaning, the only solution is to replace it.
Quartz stone surface
Quartz stone tabletop is a kind of artificial stone with new technology, which is composed of exquisite and gorgeous quartz stone. Its manufacturing process is produced by connecting a set of most advanced patent systems. This product contains more than 90% natural quartz stone or Shi Gang, combined with ultra-high performance resin and special pigment. On the basis of ensuring high hardness, high temperature resistance, acid and alkali resistance, impact resistance and easy cleaning, quartz stone countertops do not contain radioactive elements harmful to human body. Generally, quartz stone board contains up to 93% natural aging, resin, mineral pigments and other additives. The selected material forms an extremely dense complex through color matching and vacuum high pressure, and then becomes quartz stone through complex cutting and surface polishing processes. The surface of this plate is hard as granite, rich in color as marble, corrosion-resistant and pollution-resistant as glass, and the shape after coating is perfect as artificial stone.
Its main material is timely, quartz stone has no radiation and high hardness, which makes the quartz stone countertop scratch-free (Mohs hardness 7), pollution-free (vacuum-made, dense and non-porous) and non-burning (timely material). Resistant to 1300℃) high temperature, not old (30 polishing processes need no maintenance), non-toxic and non-radiation (NSF certification, no heavy metals, direct contact with food). Quartz stone countertops have various colors, and Gobi series, crystal series, granite series and shining star series are more distinctive. It can be widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc.). ) and home decoration (kitchen countertops, washstands, kitchen walls, dining tables, coffee tables, window sills, door covers, etc.). This is a kind of non-radioactive pollution.
Artificial stone table top
Artificial hillock is made of unsaturated polyester resin as binder, and marble silt or granite fragments are bonded with binder. Ordinary Shi Gang, also known as artificial marble. There are two modes of production: plate production and waste production, both of which have their own advantages and disadvantages. The former is superior in diagonal and flatness, while the latter has better color uniformity, and can also be used for special-shaped processing, such as cylindrical processing. There are many ways to produce stone in the market, such as waste production.
Product features: ① Organic pigments of different colors are mainly used in Shi Gang. Organic pigments have no tolerance to sunlight, moisture, acid and alkali, and are easy to fade or even change color. (2) The high content of glue in most stone columns, on the one hand, leads to the weak texture of stone materials, and the decorative effect cannot be upgraded; On the other hand, glue expands with heat and contracts with cold, so the product is easy to deform and warp, and its service life is short; Moreover, its glue generally contains volatile toxic gases, which is harmful to human body. (3) Due to technological reasons, Shi Gang has many pores, and the product has poor impact resistance, easy leakage and discoloration, and poor anti-pathological ability. Its gloss is fake, and it is easy to wear and tear, and it is not durable. ④ Shi Gang made of marble powder is not acid-resistant, because its main component is CaCO3, which is easy to react and decompose with acid; The hardness of marble powder and binder is very low, so the hardness of Shi Gang is also very low, generally less than Mohs hardness 3, so it is not wear-resistant, scratch-resistant and easy to scratch. ⑤ The first generation Shi Gang was more or less radioactive because it contained marble and granite.
Artificial hillock stone is mainly used for interior walls and floors, and its physical properties are not as good as natural stone and quartz stone. When using it ... >>
Question 2: How to polish the black quartz stone countertop? 1, you don't have to press the number again and again, just to be more efficient when processing. Of course, when the scratches or machining volume is large, it is necessary to choose a lower number of grinding discs. If it is too high, the effect may not be obvious;
2. After you polished it with the No.3000 grinding disc, the used stone is still there. If the scratch is deep, it can be polished with 1500 first, then with 3000 water mill, and then polished with water, which can basically solve this problem.
Question 3: How to polish Shi Ying countertops? Try to grind it as big as possible, add some water, and polish it with dry Puckilo after waxing.
Question 4: What should be used to polish the quartz table top? It must be polished with water. Grinding plates with less than 500 meshes are used for polishing, and grinding plates with more than 500 meshes are used for polishing. When the seam is uneven, it is best to grind off the high place with a 300-mesh grinding plate with water. Remember, you can only grind the high places, not the whole seam, otherwise the luster on both sides of the seam will be worn off. Finally, water is used to grind with 500-mesh, 1000-mesh, 2000-mesh and 3000-mesh millstones in turn until the joints are smooth and bright.
Question 5: The surface of the artificial quartz stone in the cupboard is half smooth and half unsmooth. Can a professional stone countertop master polish it? As for the question you mentioned, I will answer it briefly. 1. Quartz stone is a kind of superhard environment-friendly composite material, which is produced by the most advanced technology in the world. It consists of 93% natural aging and 7% mineral pigments, resins and other additives. At present, there are many brands on the market, probably hundreds. In today's competitive economic market, all these bring hidden dangers to the emerging problems. There will be no color difference in quartz stone products from authentic manufacturers. In general production, after a batch of materials are mixed, about 500 pieces of quartz stone can be produced, and some equipment will be more. In other words, these quartz stones are of the same color, and there will be no color difference. As you said, the half light is not enough. It may be a material problem. I'm not sure if it's quartz stone from a big factory. Second, quartz stone splicing can be polished, but the process is very troublesome. First, 50#, then 150#, and then 300 #; When grinding, use 500# water mill first, and then use 1000#, 2000# and 3000# water mills to grind in turn.
If this process is not realized, it will not be thrown out of the original light of the plate. Just the above two points, I hope to help you.
Question 6: What size water mill does it take to polish the quartz table top? I usually use 50100150 200 400 work and 1000 work in turn, and then put them on an angle grinder to polish them, just like where there is no joint.
I hope my answer is helpful to you.
Question 7: The usage of Shi Ying polishing agent 1. Use hard wax (strip wax), rub the strip wax on the hair ball of the polishing machine, and then move the hair ball coated with polishing wax back and forth on the table. But when polishing with a strip of wax, the corners are not very polished.
2. When using box wax and liquid wax: firstly, brush 8# wax evenly on the desktop, polish it with a polishing machine and try to clean it with clean cotton cloth, then wipe the desktop with cotton cloth dipped with 3# polishing oil to make the whole desktop evenly waxed, and then polish it with wool balls and try to wipe the corners with cotton cloth to make the desktop bright. When polishing with a polishing machine, attention should be paid to the uniformity of polishing speed, so that the polished desktop feels smooth and the visual effect is brighter.
3. In corners and corners that cannot be polished by the polishing machine, you can directly apply polishing wax with clean cotton cloth and rub it back and forth.
Question 8: Quartz stone polishing First, explain what a quartz stone countertop is. It is not a natural quartz stone, but a new type of stone synthesized by more than 90% timely crystals, resins and other trace elements. If manufacturers really produce quartz stone countertops according to this ratio and high standards, they are basically qualified, with strong hardness, anti-pollution, non-toxic and non-radiation. This is also the feeling of the quartz stone countertop you chose before.
Secondly, from the composition, we can see that the key points of quartz stone countertop quality are: first, the timely crystal is better, and the problem is not big; Secondly, the proportion of timely crystals should be appropriate, reaching 90%; Finally, the most critical point is resin. These timely crystals are bonded together by resin. Many domestic manufacturers cut corners to reduce the proportion of resin, resulting in insufficient adhesion or insufficient strength due to the use of inferior resin. Then when you use it, you will feel rough, sandy and rustle, and some will lose powder, and soy sauce will easily pollute the countertop. There will be no specular reflection under the light, and there will be a matte feeling.
There is no way to solve it in the end. Manufacturers may say that polishing and surface crystallization cannot be eradicated at all. Such a countertop is unqualified and can't be used in the environment of frequent contact with acid, alkali, salt and oil. If you want to achieve the effect of high hardness, corrosion resistance and easy cleaning, the only solution is to replace it.
One more thing to note is that the price of quartz stone countertops ranges from 100 to 1000 yuan per linear meter, mainly because of the resin. All-resin is the most expensive, such as some artificial stone series of DuPont, reaching 3-4 thousand 1 linear meter. For general household use, I think about 300 can basically meet the use. But this is a long-term use at home, and it is recommended not to give priority to the cost. After all, these rice countertops can't save much money.
Question 9: How to polish the seam of quartz stone table top of cabinet 100 minutes. Polishing process: before marble polishing, glue is applied according to the material, and then polished; Draw lines for rough grinding first, and leave 0.5MM allowance for fine grinding and water grinding during rough grinding; Mosaic: Mosaic the lines to be polished according to the installation drawing, and select and blend according to the color of the line surface to ensure the good effect of color and pattern. After polishing the 500# line, number it uniformly according to the requirements of the installation drawing, and then disassemble it for polishing, which will not cause the polished line to be uneven at the interface; When the interface is misaligned, the grinding distance of the transition section should be lengthened as much as possible, and the straightness should be checked with a ruler when grinding; When polishing marble, the polishing condition of the smooth surface should be carefully checked after each abrasive or grinding piece is polished, and the traces produced by the previous abrasive should be covered after the last grinding number is polished; When polishing marble, attention should be paid to the control of water quantity, and insufficient water quantity is easy to cause smooth burn; When polishing marble, try to stretch it along the line direction as long as possible, so as to avoid ripples; Marble polishing speed is faster; Adopt high-speed grinding and polishing electric tools.
Question 10: How are marble, artificial stone and quartz stone countertops polished? The hardness of artificial stone is not very high. Use an angle grinder, install a sticky disc, and then polish the polished workpiece (that is, circular washing sandpaper). Polished parts have different thicknesses of 120#-360#. Use 120 # for rough grinding and 180#, 240# and 360 # for fine polishing.
